WASHINGTON/ISTANBUL--The United States on Friday raised the stakes in its standoff with Turkey over Ankara's deal to acquire a Russian air defense system, laying out a plan to remove the NATO ally from the F-35 fighter jet program that includes immediately halting any new training for Turkish pilots on the advanced aircraft.
Acting U.S. Defense Secretary Patrick Shanahan sent a letter to his Turkish counterpart, seen by Reuters on Friday, that outlined how Turkey would be pulled out the program -- unless Ankara changes course.
Reuters on Thursday first reported the decision to stop accepting more Turkish pilots for training in the United States, in one of the most concrete signs that the dispute between Washington and Ankara is reaching a breaking point.
The United States says Turkey's acquisition of Russia's S-400 air defense system poses a threat to the Lockheed Martin Corp F-35 stealthy fighters, which Turkey also plans to buy. The United States says Turkey cannot have both.
Shanahan's letter explicitly states there will be "no new F-35 training." It says there were 34 students scheduled for F-35 training later this year.
"This training will not occur because we are suspending Turkey from the F-35 program; there are no longer requirements to gain proficiencies on the systems," according to an attachment to the letter that is titled, "Unwinding Turkey's Participation in the F-35 Program."
Turkish personnel already in the United States will see their training on the F-35 discontinued at the end of July.
In his letter, Shanahan also warned Ankara that its deal with Moscow risked undermining its ties to NATO, hurting the Turkish economy and creating over-dependence on Russia. "You still have the option to change course on the S-400," Shanahan wrote.
The Turkish lira declined as much as 1.5% on Friday before recovering some losses. The currency has shed nearly 10% of its value against the dollar this year in part on fraying diplomatic ties and the risk of U.S. sanctions if Turkey accepts delivery of the S-400s.
Turkey is one of the core partners in the F-35 program and expressed an interest in buying 100 of the fighters, which would have a total value of $9 billion at current prices. Turkish companies produce some 937 parts of the F-35, largely for the aircraft's landing gear and center fuselage, the Pentagon says. The United States is now planning to move that production elsewhere, ending Turkey's manufacturing role by early next year.
